Slip preventing device for vehicle

Abstract

Abstract PURPOSE:To surely prevent a driving wheel from slipping, even when a vehicle is in a fixed speed running control, by performing a traction control, in which an engine output is decreased when the driving wheel generates a slip, preferentially to the fixed speed running control in which the vehicle holds its assigned speed. CONSTITUTION:A traction ECU 31 controls a throttle valve 3 through an actuator 4 in a manner, wherein an output of an engine 1 is decreased when a driving wheel generates a slip, being based on each detection signal from each longitudinal right and left wheel speed sensor 15-18 and an accelerator sensor 33. While an autospeed ECU 32 controls the throttle valve 3 through an actuator 5 in such a manner as holding as assigned car speed being based on each detection signal from command switches of every kind 34-36, car speed sensor 37, brake switch 38, main switch 39, etc. By this constitution, when the slip of the driving wheel is detected by a means 50, the action of the traction ECU 31 is preferentially performed by a means 58.
